Susquehanna International Group (SIG), founded in 1987 and headquartered near Philadelphia, is one of the largest options market makers and proprietary trading firms in the world. It is famous for a decision-making culture rooted in game theory and poker — new traders are literally taught poker to sharpen probabilistic, expected-value thinking under uncertainty.

SIG runs large, structured early-career pipelines for assistant traders, quantitative researchers, and developers, with heavy investment in training. Because so much of its hiring is through campus programs, internships, and referrals into those pipelines, a connection who can route you to the right program meaningfully improves your odds of being seen.

How to Get a Referral: Step by Step

Target the right early-career track: SIG hires assistant traders, quantitative researchers and analysts, and software developers, each with its own structured pipeline. Have your referrer point you at the one that fits.
Lean into probabilistic thinking: SIG's culture rewards expected-value reasoning, comfort with uncertainty, and game theory. Examples of decision-making under risk — including games and competitions — resonate here.
Find a Susquehanna contact: Use FindWarmIntros to surface SIG alumni and former colleagues in your network who can flag you into the campus or experienced-hire pipeline.
Use the internship pipeline: SIG's trading and tech internships are a primary route to full-time roles; for students, an intern referrer is often the most reachable.
Prepare for probability and games: Expect probability, expected-value, and game-style questions in interviews. A referral gets you in; this preparation gets you through.

Campus pipelines dominate early hiring

Developers and quants are core

Beyond trading, SIG hires heavily for software development and quantitative research — strong technical candidates have a clear, separate path in.
